7.Fair Value Measurements

Financial instruments consist primarily of investments in cash, trade accounts receivable, debt and accounts payable. The Company estimates the fair value of financial instruments based on interest rates available to the Company and by comparison to quoted market prices. At June 30, 2014 and 2013, the carrying amounts of cash, accounts receivable and accounts payable are considered to be representative of their respective fair values due to their short-term nature. The Company's debt is considered to be representative of its fair value because of its variable interest rate.

The fair value of goodwill and non-amortizing intangibles is measured on a non-recurring basis in connection with the Company's annual impairment testing. The Company follows the guidance of Accounting Standards Update (ASU) 2011-08 and 2012-02 and performs a qualitative assessment of goodwill and non-amortizing intangibles to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  If the qualitative assessment shows that the fair value of the reporting unit exceeds its carrying amount, the company is not required to complete the annual two step goodwill impairment test.  If a quantitative analysis is required to be performed for goodwill, the fair value of the reporting unit to which the goodwill has been assigned is determined using a discounted cash flow model.  A discounted cash flow model is also used to determine fair value of indefinite-lived intangibles using projected cash flows of the intangible. Unobservable inputs related to these discounted cash flow models include projected sales growth, same store sales growth, gross margin percentages, new business opportunities, working capital requirements, capital expenditures and growth in selling, general and administrative expense and are classified in accordance with ASC 820, "Fair Value Measurements and Disclosures", within Level 3 of the valuation hierarchy.
